Patient's question:
The child has been crying non-stop recently and isn't eating much. How much should a 40-day-old baby eat each day?Doctor's answer:
Newborn babies have a very small stomach capacity (30~35ml for newborns, about 100ml at 3 months, 200ml at 6 months, and 300~500ml at 1 year), and they also secrete less stomach acid. The stomach emptying time varies depending on the type and nature of the food. For breastfeeding, the stomach emptying time is 2~3 hours, for formula feeding it is 3~4 hours, and for water it is 1~2 hours. My baby can drink 100ml of milk at this age, with an interval of 3 hours.
